Viognier is a very ancient white wine grape variety with powerful aromas of peaches, apricots, floral and herbal notes with great richness on the palate. It is indigenous to the northern Rhône Valley and famous for the tiny appellations of Condrieu and Château-Grillet which is the smallest french appellation. It is the only one grape permitted up to 20 per cent in the blend of the celebrated Côte-Rôtie wines. Apart from France, the grape has spread to California, Australia, South Africa and New Zealand. Also, very small plantings of the Viognier are found in Rioja, Priorat and south part of Bulgaria. Viognier is a quite difficult grape to grow due to the natural low acidity it has, and it is prone to disease, requires a great deal of sunshine to ripen properly and to balance between freshness, fruit and alcohol. Sometimes, exactly because of the difficult growing process leads to late harvesting, and some of the producers have sweet versions of their dry wines.
